Ok so lately I have noticed that when I start my truck, it will slightly jump forward. It's barely noticeable, but I notice even the smallest of things that are out of the ordinary... What could be the problem?

Is it fate that I just saw a very nice looking, higher mileage, 2001 Blazer Trailblazer for dirt cheap at a local used car lot?... Only thing I could see wrong with it was a bit of rust on the doors down on the lower front corner. Nothing that I couldn't get fixed for dirt cheap.

 

Ya got me stumped!
Is this with the truck in park? No codes? Trans oil clean?

 

Yup, it's on initial startup. It doesn't do it all the time. Seems really erratic. No codes either, just scanned it before I posted.

Transmission was serviced around 4000 miles ago. I need to drop the pan again anyway to install a drain plug.

 

Strange. Is this on the Bravada? or did you buy a trail Blazer?

 

It's on the Bravada.

I just stopped in and looked at an '01 Blazer Trailblazer on a used car lot at lunch today. But, its a lot more miles than my Bravada has (125k miles vs 82k miles on the Bravada) and it needs ball joints, brakes, shocks, full tune up, and it may have a rear main seal leak. All for $4900... Oh yeah, needs tires too! LOL. And I already mentioned the rust...

 

check your shift linkage. my jimmy used to do that all the time..lurch forward a small bit when i started it.

 

My 2000 blazer does the exact same thing. It just rocks forward a bit on startup. It never worries me though, I've come to accept it as a characteristic of the vehicle.

 

Ha. My truck is just saying 'Hello!' LMAO

 

Or it is dry heaving.

 

I dont think its anything to worry about. Mine does it too once in a while. More so when cold.
